y = x^2 -4x
x = -1
y = (-1)^2 - 4×-1=1+4 = 5
x= 0
y = (0)^2 - 4×0 = 0
x = 1
y = 1^2 -4×1 = 1-4 = -3
x = 2
y = 2^2 -4×2 = 4-8 = -4
x=3
y = 3^2 - 4×3 = 9-12 = -3
x = 4
y = 4^2 - 4×4 = 16 - 16 = 0
now 2nd equation
y = 2x^2 + x
x = -2
y = 2 (-2)^2 + (-2)= 8-2 = 6
x = -1
y = 2 (-1)^2+(-1)= 2-1 = 1
x = 0
y = 2(0)^2 +0 = 0
x = 1
y = 2 (1)^2 + 1 = 3
x = 2
y = 2(2)^2+2= 8 + 2 = 10
Answer:
<h2><u><em>
x = -2.27272727273</em></u></h2><h2><u><em>
in fraction</em></u></h2><h2><u><em>
x = -25/11</em></u></h2>
<u><em></em></u>
Step-by-step explanation:
Solve for X
6x+60x+150=0
66x = -150
x = -150 : 66
<u><em>x = -2.27272727273</em></u>
<u><em>in fraction</em></u>
<u><em>x = -25/11</em></u>
Answer: x= (y+z-a)/3
Step-by-step explanation:
You need to move every thing but the x on the other side, so subtract a and divide the whole thing by 3.
